Opel2_2 I have a Mk4 Astra G 2.2 and I want to upgrade to GSi 308mm brakes. Will my 16" wheels fit over them? I read somewhere I will need 17"s but I calculate the piston caliper will move 15mm and there looks to be enough room in the wheel.
Opel2_2 Thanks Mike. Don't think the internal diameter of the wheels will be an issue but the back of the spoke could be. Considering some wheel spacers, where would I get longer wheel bolts?

Opel2_2 Thanks Matt I hope 3mm is enough, Waiting for my calliper carriers to turn up then I can test fit. Might have to wait till next year as I'll be running 2 15" steels with snow tyres on the front.
